8 Supplies for Building a DIY Cattle Mineral Feeder

Keeping cattle healthy requires consistent access to essential minerals, but weather and curious livestock can easily ruin expensive loose mixes. Building your own durable mineral feeder is a cost-effective weekend project that saves money and prevents waste. With the right heavy-duty supplies, you can construct a windproof, rain-resistant feeding station that stands up to the daily abuse of a small herd.

Why Your Herd Needs a Reliable Mineral Feeder

Livestock require a steady intake of salt, calcium, phosphorus, and trace minerals to maintain optimal health, reproductive success, and strong immune systems. Simply dumping loose minerals into an open trough is a recipe for waste, as rain quickly turns expensive supplements into a useless, hardened paste. A reliable feeder keeps these vital nutrients dry, clean, and accessible in all weather conditions.

Cattle are naturally curious and incredibly strong, meaning any flimsy container will quickly be flipped, crushed, or trampled into the mud. A well-designed DIY feeder must withstand rubbing, head-butting, and shifting pasture conditions without spilling its contents. Investing a little time and effort into a rugged, home-built solution ensures your herd gets their daily nutrition while protecting your hard-earned investment in supplements.

Choosing the Right Location on Your Pasture

Placement is just as important as the construction of the feeder itself. To ensure your herd actually uses the mineral station, position it near high-traffic areas such as water troughs, shade trees, or favorite loafing spots. If cattle have to walk too far out of their daily routine to find minerals, consumption rates will drop significantly.

Avoid low-lying, poorly drained areas where rainwater pools and mud accumulates, as heavy cattle hooves will quickly churn the surrounding soil into a deep, messy mire. Placing the feeder on a slight slope or a well-drained gravel pad helps keep the area dry and accessible. Rotating the feeder’s location periodically also prevents localized pasture damage and soil compaction.

Plastic Drum – Mauser 55 Gallon Open Head Poly Drum

The main body of a DIY mineral feeder needs to be incredibly tough, weather-resistant, and spacious enough to house a feeding tub while allowing easy access. A heavy-duty plastic barrel serves as the perfect protective shell, shielding the minerals from driving rain and wind. Cutting an entry window into the side of the barrel allows cattle to stick their heads inside to feed while keeping the elements out.

The Mauser 55 Gallon Open Head Poly Drum is the ideal foundation for this project because of its thick, high-density polyethylene (HDPE) construction that resists cracking in freezing temperatures. Its open-head design with a removable lid and metal lever-lock ring makes filling and cleaning the feeder incredibly simple.

• Capacity: 55 gallons
• Material: Food-grade high-density polyethylene (HDPE)
• Closure: Heavy-duty steel lever-lock ring
• UV Resistance: Excellent for long-term outdoor exposure

When prepping this drum, ensure you smooth down any rough edges left from cutting the entry hole to prevent cattle from scratching their faces. This specific barrel is perfect for small-scale farmers who want a long-lasting, low-maintenance base, but it may require extra anchoring in extremely high-wind areas due to its lightweight nature when empty.

PVC Pipe – Charlotte Pipe 6-Inch Schedule 40

To prevent cattle from knocking the feeder over or dragging it across the pasture, you need a strong central sleeve that allows the feeder to rotate or slide over an anchoring post. A thick-walled PVC pipe serves as this internal protective conduit, shielding the anchor line or post from direct contact with the cattle and the elements.

The Charlotte Pipe 6-Inch Schedule 40 PVC pipe provides the structural rigidity required to withstand the constant pushing and rubbing of heavy livestock. This industrial-grade pipe is highly impact-resistant and will not crush under pressure, making it far superior to thin-walled drainage pipes.

• Diameter: 6 inches
• Wall Thickness: Schedule 40 (heavy duty)
• Material: Polyvinyl chloride (PVC)
• Length Options: Easily cut to custom heights with a standard hand saw

Before installing, make sure to deburr the cut ends to ensure smooth movement over your anchoring post. This pipe is ideal for farmers building a rotating wind-vane style feeder, though it requires a heavy-duty saw or rotary tool to cut through its thick walls during assembly.

PVC Cap – Charlotte Pipe 6-Inch Dome Cap

Rainwater finding its way into the internal support structure of your feeder can lead to rusted anchor posts, stagnant water buildup, and premature wear on moving parts. A tight-fitting cap is essential to seal off the top of the central PVC sleeve, keeping the interior dry and functional year-round.

The Charlotte Pipe 6-Inch Dome Cap is designed to fit perfectly over Schedule 40 pipe, creating a watertight barrier that sheds rain effortlessly. Its rounded dome design prevents water from pooling on top, and its heavy-duty PVC construction ensures it won’t crack under intense summer sun or freezing winter temperatures.

• Size: 6-inch socket connection
• Shape: Domed top for water runoff
• Compatibility: Fits standard Schedule 40 PVC pipes
• Installation: Can be solvent-welded or secured with screws

For a DIY feeder, securing this cap with removable self-tapping screws rather than permanent PVC cement is a smart move, allowing you to access the internal anchor post for maintenance if needed. This cap is a must-have for anyone building a post-mounted feeder, though it is unnecessary if your design relies purely on suspension chains.

Rubber Tub – Fortex 15-Gallon Utility Pan

The container holding the loose minerals sits at the very bottom of the feeder, where it must endure constant licking, nose-butting, and occasional stomping. Hard plastic tubs will quickly crack under this abuse, wasting minerals and potentially injuring your livestock with sharp edges. A heavy-duty, flexible rubber pan is the only material that can survive this environment.

The Fortex 15-Gallon Utility Pan is molded from a rubber-fiber composite that is virtually indestructible, resisting crush damage even if a cow steps directly on it. Its low profile and wide base fit perfectly inside the bottom of a 55-gallon drum, providing a stable reservoir that won’t easily tip over.

• Capacity: 15 gallons
• Material: Real rubber reinforced with cord
• Weathering: Crack-proof and freeze-proof
• Safety: Food-safe and crush-resistant

Ensure you clean this tub thoroughly before its first use to remove any manufacturing residues that might deter picky cattle from eating their minerals. This pan is perfect for any DIY feeder setup, though its heavy weight means you should secure it to the bottom of the drum to prevent cattle from lifting it out.

Rubber Mat – StallMatts 4×6 Foot Utility Mat

The area directly in front of a mineral feeder experiences intense hoof traffic, which can quickly turn the ground into a muddy, eroded mess. Additionally, cutting a heavy, flexible flap to cover the feeder’s opening helps keep driving rain out while allowing cattle to easily push their heads inside. A durable rubber utility mat solves both of these problems beautifully.

The StallMatts 4×6 Foot Utility Mat is made from dense, recycled rubber that provides an excellent non-slip surface for cattle to stand on while feeding, protecting the pasture soil from erosion. Alternatively, sections of this thick mat can be cut down to create heavy-duty, self-closing weather flaps for the drum’s entry window.

• Dimensions: 4 feet by 6 feet
• Thickness: 3/4-inch heavy-duty rubber
• Texture: Non-slip, textured surface
• Durability: Resistant to tearing, weather, and heavy hoof traffic

Cutting this thick mat requires a sharp utility knife and some patience, but the durability it offers is unmatched by thinner materials. It is an essential investment for farmers dealing with wet, muddy spring pastures, though its weight makes it cumbersome to move once positioned.

Eye Bolt – National Hardware 1/2-Inch Lag Eye

To hang your feeder from a tree limb or a sturdy wooden frame, you need a rock-solid connection point that won’t pull out under the weight of the feeder and the pressure of rubbing cattle. Cheap, thin hardware will quickly bend or shear off, risking a collapsed feeder and wasted minerals. A heavy-duty steel eye bolt provides the secure anchor point needed for suspension.

The National Hardware 1/2-Inch Lag Eye features deep, sharp wood threads that bite securely into wooden posts or overhead beams, ensuring a permanent hold. Its galvanized finish protects it from rust and corrosion, which is critical when exposed to outdoor humidity and acidic mineral dust.

• Diameter: 1/2-inch shank
• Material: Weather-resistant galvanized steel
• Thread Type: Lag thread for wood mounting
• Load Rating: High working load limit suitable for livestock equipment

Note: Ensure you pre-drill a pilot hole before driving this heavy bolt into treated lumber to prevent the wood from splitting.

This eye bolt is perfect for hanging setups, but if you are mounting your feeder directly to a metal T-post, you will need to swap this lag-thread bolt for a machine-thread eye bolt with matching nuts and washers.

Coil Chain – Campbell Chain 1/4-Inch Grade 30

Hanging your mineral feeder allows it to swing freely when bumped, absorbing the impact of rowdy cattle rather than breaking under tension. Rope will quickly rot, stretch, or get chewed on by curious livestock, making a strong steel chain the only reliable choice for long-term suspension.

The Campbell Chain 1/4-Inch Grade 30 proof coil chain provides the perfect balance of strength and flexibility for hanging outdoor feeders. Its galvanized finish ensures it won’t rust solid in wet weather, and its high working load limit easily handles the weight of a fully loaded barrel.

• Size: 1/4-inch trade size
• Grade: Grade 30 proof coil
• Finish: Hot-dip galvanized for superior rust protection
• Versatility: Easy to adjust height using quick links or shackles

When hanging the feeder, ensure the chain is kept taut enough to keep the barrel off the ground but low enough for calves to reach the opening comfortably. This chain is ideal for hanging setups, though you will need a pair of bolt cutters or a hacksaw to cut it to your desired length during installation.

Deck Screws – Grip-Rite PrimeGuard 3-Inch

A DIY feeder is only as strong as the fasteners holding it together. Standard wood screws will quickly rust and snap under the constant vibration and moisture exposure of an outdoor pasture. You need heavy-duty, coated screws that can bite deep into wood and plastic without backing out over time.

Grip-Rite PrimeGuard 3-Inch deck screws feature a premium polymer coating that offers top-tier corrosion resistance against both weather and the corrosive nature of loose livestock minerals. Their star-drive head prevents cam-out during installation, allowing you to drive them tightly into dense materials.

• Length: 3 inches
• Coating: PrimeGuard Ten-Year Nano-Coating
• Drive Type: Star drive (T25) to prevent stripping
• Thread: Coarse threads for maximum holding power

Always use washers under the screw heads when securing soft materials like the rubber mat flaps to prevent the screws from pulling through the rubber over time. These screws are a staple for any farm workshop, though they do require a matching star-drive bit to install.

Step-by-Step Assembly Tips for Your Feeder

Start by thoroughly cleaning your Mauser poly drum and marking out a large entry window on one side, roughly 12 inches wide and 18 inches high, keeping the bottom of the cut at least 8 inches from the base to retain the mineral tub. Use a jigsaw to carefully cut out the opening, then use heavy-grit sandpaper or a utility knife to smooth down any sharp plastic edges to protect your cattle’s faces.

Next, place your Fortex rubber tub inside the bottom of the drum. To keep the tub from shifting, secure it to the bottom of the barrel using a couple of short bolts with wide fender washers. If your design uses a central rotating post, slide your Charlotte Pipe PVC sleeve through the center of the drum and lid, securing it with heavy-duty brackets and your Grip-Rite screws.

Finally, cut a section of the StallMatts rubber mat to act as a weather flap over the entry window, mounting it above the opening with a wooden strip and deck screws so it hangs freely. Attach your National Hardware eye bolt to the top lid or your hanging frame, connect the Campbell coil chain, and hang the feeder at a height where your smallest calves can easily push the flap open to feed.

How to Secure and Maintain Your DIY Feeder

Even the sturdiest DIY feeder will fail if it isn’t properly secured against the enthusiastic rubbing of a 1,200-pound cow. If you are hanging your feeder, ensure the support branch or wooden frame is rock-solid and check the chain connections monthly for wear or loosening. For ground-based rotating feeders, drive a heavy steel T-post deep into the ground, slide the PVC sleeve over it, and ensure the barrel rotates smoothly to face away from the wind.

Maintenance is simple but crucial for keeping your minerals fresh and appetizing. Check the feeder weekly for any moisture intrusion, dumping out any clumped or spoiled mineral mix immediately to prevent mold growth. At least twice a year, wash the internal rubber tub with soapy water, rinse it thoroughly, and let it dry completely before refilling it with fresh mineral mix.

Keep an eye on the rubber weather flaps and replace them if they become stiff or torn from heavy use. Regularly checking and tightening the deck screws and eye bolts will prevent structural failures, ensuring your DIY feeder remains a reliable, cost-saving asset on your pasture for years to come.

Building your own cattle mineral feeder is a rewarding project that keeps your herd healthy while protecting your wallet from wasted supplements. By using durable, weather-resistant materials like heavy-duty poly drums, flexible rubber tubs, and galvanized hardware, you can construct a feeder that stands up to the elements and livestock abuse. With a little weekend effort, you will have a reliable feeding station that serves your pasture for seasons to come.
